BEAM WARPER.

Application filed September a, 1926. Serial No. 134,401.

invention has relation to beam The warpers; that is to say, to warping machines of the class employed forwmding upon. a beam a series of yarns or threads-assembled in the manner, etc, usual in the case of the preparation of a warp for use in weaving.

In practice, a receiving-beam in a beam warper is rotated, for the purpose of winding the series of yarns or threads upon it, thro h contact between the periphery of the wouiid mass upon the beam and the periphery of a power-driven friction-drum. This peripheral driving engagement is utilized be cause it produces a rate of winding which is uniform throughout all stages in the increase of diameter of the wound mass, avoiding gradual increase in the density of the wound mass from the center outward.

In some cases, for the purpose of enabling yarns or threads to be wound into a mass of predetermined density, either firm and compact or soft and porous, whichever may be desired, beam warpers are equipped with means for giving to the yarns or threads as they are wound on the beam a definite state of tension which will secure the desired density of the wound mass. This means consists of a roller with which the yarns or threads engage just prior to being wound on the beam, and which is driven with a surfacespeed bearing such relation to the surfacespeed of the wound mass that the rate at which the yarns or threads are wound upon the beam will impart the required tension to the yarns or threads as they wind upon the beam, and thereby .produce the desired condition in the wound mass.

The invention consists in a beam warper having a friction-drum, a positively-driven tension-controlling roller, and improved means for driving the said roller with capacity for regulation at will of the ratio between the surface-speed of the said roller and that of the friction-drum. More specifically stated, the invention consists in a beam warper comprising a friction-drum for the actuationof a receiving-beam or the like'and a tension-controlling roller, and characterized by having the tension-roller operatively combined with the'friction-drum by means of a direct driving train extending from the latter to the former and including manuallyadjustable speed-varying means by which the ratio of the surface-speed of the tension-controlling roller with respect to that of the friction-drum may be regulated at will tion is shown in the accompanying drawings,

in which latter,

Fig. 1 1s a yiew in side elevation of a warper contammg the said embodiment.

Fig. 2 is a view thereof in vertical section in a plane parallel with the side-frames.

Fig. 3 is a partly-sectional elevation of the speed-varylng means, on a larger scale than Figs. 1 and 2.

Fig. 4 is a partial front elevation of the warper.

In the drawings, a friction-drum is shown at 1, with a receiving-beam in working relation therewith, and a tension-controlling roller is shown at 2. The shaft 11 of the friction-drum 1 is shown mounted as usual in bearings 12, 12, in connection with the lower portions of the side-frames 3, 3, of the machine. The journals of the tension-controlling roller 2 are mounted in bearings in connection with the upper portions of the said side-frames. In practice, rotary motion is imparted to the said friction-drum by means of power applied to the shaft 11 through suitable driving connections (not shown). The direct driving train by means of which the tension-controlling roller is rotated from the friction-drum is shown in Figs. 1, 3, 4C and described hereinafter. I

For controlling the position of the receiving-beam so as to hold its barrel 4, Fig. 2, proper working relation with respect to the periphery of the friction-drum, the journals of'its shaft 5 in this instance are shown seated in open-topped bearings at 6 in connection with forwardly projecting arms 61 of lovers which are mounted pivotally at 62 upon the side-frames 3, 3. By reason of the levers being capable of swinging around the pivots or fulcrums 62 the beam is enabled to gravitate toward the friction-drum sothat the periphery of the beam-barrel, or that of the mass of yarns or threads wound on such balancing the combined weigllt of the beam and the load 7 of yarns or threads wound thereon, so as to diminish the force with which the exterior of the wound mass presses against the periphery of the friction-drum,

- and thereby guard against too much 'eom pression of the wound mass as the yarns or threads 8 are wound upon the beam. The weights 63, 63, may beadded to from time to time in proportion as the size and weight of the-wound mass increase, in order to equalize the counterbalancing function throughout the filling of the beam, or for suchpurpose may be shifted on the lever-arms 621 away from the lever-pivots or fulcrums 62. This weighted-lever arrangement is not included in the present invention.

The tension-controlling roller 2 is located near the position of the receiving-beam so that it controls the tension of those portions of the yarns or threads which are intermediate the roller itself and the place at which the yarns or threads are received by the periphcry of the wound mass on the beam. Guiderolls 9, 9, Fig. 2, at the rear and front, respectively, of the tension controlling roller cause the yarns or threads to encircle a substantial portion of the periphery of the said roller, to ensure more effective engagement between the yarns or threads and the said periphery, and enable the roller to control the in the form thereof which is illustrated in Figs. 1, 3 and 4 of the drawings the following elements:

A spur-gear 13 is fixed upon one end of the I shaft 11 of the friction-drum. A spur-pinion 14 is mounted upon a support 15 in connection with the adjacent side-frame 3, and in engagement with spur-gear 13. A cone-pulley 16 in fixed connection with the said spurpinion 14 is mounted upon the said support 15 to turn in unison with such spur-pinion. A second cone-pulley 17, and connected spurpinion, 18, are mounted to turn in unison upon a support 19 in connection with the said side-frame. A belt, 20, applied to the two cone-pulleys serves for transmitting rotary motion from the first cone-pulley, 16, to the second thereof, 17. A carrier-pinion 191 is mounted upon a support 201 in connection with the said side-frame, and a spur-pinion 21 is fixed upon the adjacent journal of the tension-controlling roller 2, the said carrierpinion being in engagement with the twodrum may be varied at will through a shift of the cone-belt 20 in the direction of the length of the cones. This shift is provided for in the present instance by means of beltshifting devices comprising a shifter-fork, 22, through which the cone-belt passes, and a fork-shifting screw 23 provided with a handwheel 24 through which it may be turned manually in effecting adjustment of the shifter-fork lengthwise of the cones. At 25 is shown a guide-bar upon which the shifterfork slides as it is moved inward and outward by means of the adjusting screw 23.

Within the scope of the invention as defined in the following claims, the constructional embodiment of the invention may be modified more or less in practice.

What is claimed as the invention is:--

1. Ina beam-warper including a frictiondrum mounted to rotate in stationary bearings and adapted for the actuation of a receiving beam or the like on which frictiondrum the said receiving drum rests so as to derive support therefrom in addition to being actuated thereby, and a tension-controlling roller adjacent the winding-point in the machine, the combination comprising the said friction-drum, the said tension-controlling roller, and a driving train through which the roller is driven from the friction-drum, and manually-adjustable speed-varying means between the friction-drum and the roller by which the ratio of the surface-speed of the tension-controlling roller with respect to that of the friction-drum may be regulated at will through manually-effected adjustment in the connections between the friction-drum and the said roller.

2. In a beam warper, the combination with a beam-actuating drum mounted to rot-ate in stationary bearings, and a tension roll for the yarns, of a cone geared to the said beam, :1. second cone in driving connection with the said tension roll, a cone belt connecting the said cones, and means for adjusting said cone belt upon the cones to vary the relative peripheral speed of the tension roll with reference to that of the drum. l
